To all whom t may concern: f

Be it known that I, HARRET HILL, a citizen of the United States, and a resident of the city, county, and State of New York, (whose post-office address is 329 .Lexington avenue, New York city,). have invented a new and useful Improvement in Paper- Vessel-Making Machinery, of which the following is a specification.

The object of my invention is to provide a suitable machine for turning out paper bowls and similar paperarticles which are in which made from'a' circular blank by means of a plunger which is pressed through a suitable 1e and attendant mechanism. This and other objects are accomplished by my invention, one embodiment of which is hereinafter more particularly set forth.

For amore detailed description of my invention, reference Iis to be had to the accompanylng drawings, forming a part hereof,

Figure l! is a plan view of my improved machine.

Fig. 2 is an enlarged elevation of a portion of the same.

\,Fig. 3 is a side elevation opposite the side shown inv Fig. 2, the scale 'being the same as inFig. 1.

Fig. 4 is a sectional viewshowing a cam 5*5 of Fig. 2, looking in the direction 0f the arrows.

Fig. 6 is' a sectional jview through the die and plunger, which. section is also taken on the line of Fig. 5, looking in the direction of the arrows.

Fig7 is another sectionalview taken substantially on the line 6-6'of Fig. 5,'looking in the( direction of the arrows, but more extensive than Fig. 6 and shows the plunger in a different position. i

Fig. 8 is a sectional view showing the feed rollers in a different position from that occupied by them in Fig. 7.

Figs. 9 and 10 are fragmentary views showing a plan and side elevat1on, respect1vely, of the vessel made by this machlne.

Throughout the various views of the drawings, similar reference characters designate similar parts.

My improved vessel making machine 1s provided with a suitable (base 2 from which rise suitable supports for the various elements of the machine. At one end are lo.- cated suitable pedestals 3 which carry the main shaft 4 of the machine. Power is derived through an ordinary pulley 5 which is fixed on this shaft, as is also a small pulley 6 for driving the feed rollers, acam l7 for shifting the support for f one of the feed rollers, crank arms 8 which are connected by a crank pin 9 for driving a pitman 10, which is connected to the main plunger of themachine, through a pin 11 and cam 12 for driving a part of thc feeding mechanism and a crank 13 for driving a pneumatic mechanism connected with the blank feed.`

The pitman 10 runs tothe pivot `pin 11 in a suitable cross head 14 onfthe plunger 15, and this cross head is mounted to slide freely inl a suitable cross head guide 16 that rises which consists of a supporting .block 17 that has a number of slots therein and in each slot is pivotally mounted an arm 18, which has its outer end pivotally connected to alink 19 which runs to a Sliding block 20, where it is pivotally connected, and this block 20 slides on the plunger 15 and is actuated by an armJ 21 which is connected thereto and also to a sliding shaft 22 which slides in the direction of its length in suitablev guides 23 mounted on the base 2. In

the active directionthis shaft 22 is moved by a coil spring 24 which has one end fixed to an upright coming from the base 2 and the other end to the shaftand in the other direct/ion this shaft is movedl by the arm 21 which is shoved by the block 20 which in turn` is shifted by the `block 17 onthe end of the plunger 15.

The arms 18 coperate with corresponding grooves 25 of a die 26, which is held in a suitable support 27 fixed tothe base 2. This die 26 is Iflared substantially as shown and provided Awith shoulders 28 in the corruga;

Ations which prevent the 'finished article from being withdrawn by the return movement of the plunger 15 and its connected parts. In its extreme front end this die 26 is provided with a suitable guard 29 which is fixed thereto and placed so as to recelve and support La blank 30 just before the plunger 15 and.' its connected parts act on the same. This `guard isf recessed at 31 to receive the arm 21Y at the forward limit of its movement. The rear end of the die 26 dred nested vessels,

shape.

.` rent from any suitable source, not shown.

From the sleeve 32, the finished vessels are thrust into a suitable trough 34, which is supported by brackets 35, which rise from the bed 2, or in any other suitable way. This trough is ofany desired length and is made long enough to receive any convenient num-v ber of complete paper' vessels so that an attendant may attend several machines while a number of vessels are accumulating.

ln view of the foregoing, it will be understood that the rotation of the shaft 4 caiisesf a rotationof the cranks 8 with a corresponding `oscillation ofthe pitman l0 andv reciprocationfof the cross head 14 with the attendant movement of the plunger 15, which' is ixed'thereto. IThe die 26 is also fixed and placed so as to coperate with the arms 18 and block 17 on the plunger 15, as above described, so that as this plunger continues its motion, and passes through the die 26, the' vessel just made is caught in the die by having its' rear edge against the shoulders 28 and thereafter the piston 15, with its connected parts, is withdrawn-.and a new blank is brought A'so-rest on the guide 29 and the operation isv repeated and the sec? fond lvessel is nested in the rst, and this cycle is repeated as long as the machine operate's.

'The blank 30-is fed automatically to v the die in-,a mannerV which will now be described,

and by mechanism which willbe explained.

Rising from the bed 2 are two parallel uprights 36 which at their top carry the inclined table l37 on which the blanks 30 arev placed in aA pile which is kept properly are supported spille.

centered by means of suitable guides 38 which are adjustably mounted on the table and about the center. There' is an opening 39 at the center ofthe table 37 and below this are twoinclined guides 40. The blanks in'this opening, before they are in motion,

guide the lowest blank when its movement is initiated by a mechanism -which will be described below.

In the embodiment Aof my invention here'- in setv forthptbe lowest blank is removed after being separated from the rest of the It is separated by means of an air blast directed vby a nozzle 41 supported on' thelower surface-of the table, 37 and directedtoward' the center of the opening 39, 1 This nozzle 41 is co'n.

and pivotally connected on these guides and: Athey nected to atube' 42 which runs to one end of a cylinder 43 which has a piston slid ing therein, .which is Aconnectedto the rod 44 in the conventional way and this rod 44 runs to the crank 13 on the shaft 4 so that the piston in the cylinder 43 operates in unison with the shaft 4 and the cams and cranks connected therewith. Obviously; the blast of air blown at the edges of the blanks 30, separates them to a slight degrec, and'while thisseparation is taking place, the twin suction nozzles 45 (see Figs. 8 and 7) face of the lowest'blank. and then swung downwardly so as to-bring this blank with its lower edge nearly vertical and between feed rollers 46 and 47 which are-separated until the blank is in place between them, and then these'rollers are brought together and feed the blank to its positionk of rest on the guide 29 where' it is operated on, as above described. Suction is obtained for the nozzles 45 by means of a hollow shaft 48, on which they are mounted and this shaft `is allowed tooscillate but is so formed are brought against the lower sur-l that while it oscillates, it yhas its opening connected to a pipe 49 which runs tothe rear end of the cylinder`43, thatis the end removed from that to which the tube 42 runs. From-this it is obvious that .as the piston ijeciprocatesA on the piston rod 44, the tube 42 supplies anl air tube 49 supplies an exhaust, and conversely when the tube 42 supplies an exhaust, the tube 49 supplies a blast which acts to separate the nozzles 45 from the blankto which they have been. secured.' Theapparatus is so timed that the blast in the nozzles 45 takes place at the time the feed rollers 4 6 and 47 press the blank and begin to operate and when they do this, they draw this blank over the guides. 40 and force this blank into'place on the guide 29, as above described. The shaft '48 is oscillated by means of a crank 50 which is fixed thereto, to a link' 51, which runs to an arm 52, which v.is pivotally mounted atl'the top of an upright 53 on the vbed 2 and provided with a pintle roller 54 which is adapted to engage the cam 12. This arm 52 is provided with an extension 55, which extends to nearthe table 2, and atjits end,l it is provided with a coil spring 56 which connects it with an upright on this table so that under-'normal conditions, the pintle 54 is kept against the cam 12 at all blast while the times so that the shifting of the rod 51 y will be governed by the cam. The cam 12 is 'so shaped that the nozzles 45 are drawn so as to properly discharge their functions as above des,criloed.= y

The feed rollers 46-and 47 rotate vcontinuously and are mounted on suitable parallel shafts 57 and 58 respectively, the former being journaled in the uprights 36 and tlie latter in a movable frame 59, which is pivotallylmounted on pins 60 set in the uprights 36. The shafts 57 and 58 are provided with small pulleys 61 and 62 respectively which are driven by one long belt 63 which runs over the, pulley 6 and also over idle pulleys 64, 65 and 66. The two latter' pulleys are mounted on a spindle 67 which extends from the frame 36 and the pulley 64 is mounted on a bracket arm 68, which is pivotally mounted on the upright 36 so that at all times the belt 63 has proper tension. t is necessary to provide `a tensioning means ybecause of the oscillations of the frame 59, which oscillates by means which will now be described. A link 69 is pivotally connected to this frame 59 near its upper end, or in any other suitable place, and extends to the front of the machine where it is pivotally connected to a short arm 70, which is pivotally connected at its upper end to an upright- 71 on the table 2. This arm also carries a pintle 72 which engages the cam 7 on the shaft 4. A spring 73 runs from the upright 71 to a projection 74 fixed to the link 69 so that under all conditions of service, the pintle 72 is held in contact with the cam 7.v This cam is so shaped that the frame 59 is swung away from the shaft 57 when the blank is fed as above described, and brought back toward this shaft and kept near this shaft throughout the remainder of the feed of the blank so that the rollers 46 and 47 may properly coperate. A suitable guard 75 is provided on the frame 59 for preventing the blank from gettin caught or injured while passing through te feeding mechanism, as above described.

In view of the foregoing, the operation of my improved machine w1ll be readily understood. A pile of blanks is put in position and t-he machine is started. A blast of air through the nozzle 46 separates the last blank from its fellows at its forward edge and while this separation occurs the suction through the nozzles-45, holds these nozzles to the lower surface of this blank and then these nozzles are thrown downwardly so as to bend the blank and place its lower end where it gets between the rollers 46 and 47 and release it because of the blast and then these rollers feed the blank to the guide 29, where it comes to rest. The plunger 15, with its attendant mechanism, then acts as above described to force the blank through the die 26vin the proper manner and then the plunger is withdrawn and meanwhile the feeding mechanism has acted so that as soon as the plunger has withdrawn, a

second blank is fed as before and this cycle of operations is repeated indefinitely so that finished vessels, after being kept in a heated condition in the die and sleeve 32 long enough to receive their proper shape and set, enter the trough 34 where they accumulate until removed by the operator and packed.

lVhile I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claims.

lVhat I claim is:

1. In a machine of the class described, a plunger, an expander mounted on said plunger, a fixed die adapted to receive said plunger, a shoulder in said die adapted to engage an edge of a vessel formed between the die and plunger and prevent the vessel from returning with the plunger when the same is withdrawn from the d1e, and means for removing a blank from a pile and feeding it between the die and plunger.

2. In a machine of the class described, a plunger having an expander, and a fixed die having corrugations with notches therein, and means for forcing the plunger and its expander through the die to form a vessel which engages said notches so that .the plunger may be withdrawn without wlthdrawing the vessel.
